In this game process, a core story or scenario is set in advance, and an action role-playing game is executed in which the game is advanced according to the story or scenario.

In the game processing, the CPU 81 sequentially receives biometric data from the biometric information acquisition device 7 via the upper terminal 31. Before the start of the game, the CPU 81 outputs healing music and displays beautiful pictures in order to put the player's psychological state into a "relaxed state", and the initial values of the player's pulse wave and pupil size. Acquire (calibrate) (initial value of biometric information). Then, the CPU 81 sets a baseline for determining whether the sympathetic nerve is dominant or the parasympathetic nerve is dominant based on the initial values of the pulse wave and the pupil size of the player.

After the game starts, the CPU 81 sets the target psychological state in the psychological state flag according to the situation of the game being played (content being played). Specifically, when the character is moving and searching the grassland, the CPU 81 sets “1” indicating “concentrated state” as the target psychological state in the psychological state flag. Further, when the character is in a situation of fighting with a monster, or in a situation of moving or searching a dungeon, the CPU 81 sets "2" indicating an "excited state" as a target psychological state. Set to the psychological state flag. Further, when the character is fighting with the boss monster in the dungeon, the CPU 81 sets “3” indicating “stress state” as the target psychological state in the psychological state flag. Then, when the scene is changed after the capture and the situation is changed to a new map, the CPU 81 sets “0” indicating “relaxed state” as the target psychological state in the psychological state flag.

Further, the CPU 81 identifies the psychological state of the player from the combination of biological information such as the pulse wave, the brain wave, and the change of the pupil of the player. Specifically, the CPU 81 determines whether or not the pulse wave of the player specified from the pulse wave data included in the biological data is equal to or higher than the baseline. Further, the CPU 81 determines whether the player's brain wave specified from the brain wave data included in the biometric data is an α wave, a β wave, a γ wave, or a θ wave. Further, the CPU 81 determines whether or not the size of the pupil of the player specified from the pupil data included in the biometric data is expanded beyond the baseline. Then, the CPU 81 identifies the psychological state of the player from the combination of biological information such as the pulse wave, the brain wave, and the change of the pupil of the player determined in this way.

FIG. 4 is an explanatory diagram illustrating the relationship between biological information and psychological state.

As shown in FIG. 4, in the CPU 81, when the size of the player's pulse wave and the pupil are both less than the baseline (when the pulse wave is reduced and the pupil is reduced), that is, the parasympathetic nerve is dominant. In this case, if the brain wave of the player is an α wave, the psychological state of the player is determined to be a “relaxed state”, while if it is a θ wave, it is determined to be a “bored state”. On the other hand, in the CPU 81, when the size of the player's pulse wave and the pupil are both equal to or larger than the baseline (when the pulse wave is increased and the pupil is enlarged), that is, when the sympathetic nerve is in a dominant state. If the brain wave of the player is a β wave, the psychological state of the player is determined to be an “excited state”, while if it is a γ wave, it is determined to be a “concentrated state”. Further, if the duration t of the "excited state" is T1 or more, the CPU 81 determines the psychological state of the player as the "stress state", and further, if the "stress state" continues for T2 or more, that is, "excitement". If the "state" continues for a predetermined period of T1 + T2 or more, the CPU 81 determines the psychological state of the player as the "fatigue state".

Then, the CPU 81 changes the game mode so as to set the target psychological state set in the psychological state flag.

Specifically, when the psychological state flag is set to "1" indicating "concentrated state" and the player's psychological state is "relaxed state" or "boredom state", it is assumed that the player shows signs of boredom. , In order to make the psychological state of the player "concentrated state", the game mode is changed so that the sympathetic nerve is enhanced and the sympathetic nerve becomes dominant. For example, a herd of animals different from the monster may appear, or a relatively weak monster may appear.
On the other hand, when the psychological state of the player matches the psychological state set in the psychological state flag in the "concentrated state", the game mode is not changed in order to maintain the "concentrated state". That is, as usual, it displays a vast space and a landscape of grasslands, and outputs a calm BGM and natural environmental sounds.
On the other hand, when the psychological state of the player is the "stress state", the game mode is changed so that the sympathetic nerve is suppressed in order to return the psychological state of the player to the "concentrated state". For example, display a special scene for a cooldown in the game.
In addition, when the player's psychological state is "fatigue state", it is impossible to immediately return the player's psychological state to "concentrated state", and advice (instruction) is given to interrupt the game and rest the body. Display the screen.

When the psychological state flag is set to "2" indicating "excited state" and the psychological state of the player is any of "relaxed state", "boredom state", and "concentrated state", the psychological state of the player In order to make the game "excited", the game mode is changed so that the sympathetic nerve is enhanced. For example, if you are in battle with a monster, a reinforcement monster will appear, and if you are moving or exploring a dungeon, you will output a sound effect or suddenly make a monster appear.
On the other hand, when the psychological state of the player matches the psychological state set in the psychological state flag in the "excited state", the game mode is not changed in order to maintain the "excited state". That is, as usual, while moving and exploring the dungeon, the disturbing atmosphere of BGM and sound effects for giving anxiety and tension is kept sounding.
On the other hand, when the psychological state of the player is the "stress state", the load on the player is considered to be too large, and the game mode is changed so that the sympathetic nerve is suppressed in order to return the psychological state of the player to the "excited state". conduct. For example, reduce the strength of the monster if you are in combat, and display clues that indicate the correct route if you are moving or exploring the dungeon.
In addition, when the player's psychological state is "fatigue state", it is impossible to immediately return the player's psychological state to "excited state", and a screen is displayed to advise the player to interrupt the game and rest. do.

When the psychological state flag is set to "3" indicating "stress state" and the player's psychological state is any of "relaxed state", "boredom state", "concentrated state", and "excited state". , In order to make the psychological state of the player into a "stress state", the game mode is changed so that the sympathetic nerve is enhanced. For example, you can spawn reinforcement monsters, temporarily strengthen boss monsters, or temporarily weaken your character.
On the other hand, when the psychological state of the player is the "stress state", the game mode is not changed in order to maintain the "stress state". In addition, while providing certain support such as canceling the disadvantageous state such as paralysis of the character and giving advantageous items to the character to prevent it from becoming "fatigue state", do not provide excessive support. The game mode may be changed to maintain the "stressed state" by preventing the player from returning to the "relaxed state", "boredom state", "concentrated state", and "excited state".
In addition, when the player's psychological state is "fatigue state", it is impossible to immediately return the player's psychological state to "stress state", and a screen is displayed to advise the player to interrupt the game and rest. do.

When the psychological state flag is set to "0" indicating "relaxed state", and the player's psychological state matches the psychological state set in the psychological state flag in "relaxed state", it is regarded as calm and "relaxed". Do not change the game mode to maintain the "state". For example, as usual, it displays vast spaces and grassland landscapes, and outputs calm BGM and natural environmental sounds. Then, after a certain period of time, you can start a battle with Monsta or a new quest.
On the other hand, when the psychological state of the player is "bored state", the game mode is changed so that the brain wave becomes an alpha wave in order to make the psychological state of the player "relaxed state". For example, a herd of animals different from the monster may appear, or a natural environmental sound or landscape change may occur.
On the other hand, when the player's psychological state is one of "concentrated state", "excited state", and "stressed state", the sympathetic nerve is suppressed and the parasympathetic nerve is suppressed in order to return the player's psychological state to the "relaxed state". The game mode is changed so that the player becomes superior. For example, it displays vast spaces and landscapes of grasslands, and outputs calm BGM and natural environmental sounds.
In addition, when the player's psychological state is "fatigue state", it is impossible to immediately return the player's psychological state to "relaxed state", and a screen is displayed to advise the player to interrupt the game and rest. do.

Next, the game processing executed by the game system 1 having the above configuration will be described with reference to the drawings.

The CPU 81 executes a game process by executing a game program stored in an external storage medium or the like installed in the slot 23.

FIG. 5 is a flowchart showing the details of the game processing.

In the game processing shown in FIG. 5, the CPU 81 determines whether or not the game has ended (step S51).

If the game is finished (step S51; Yes), the CPU 81 ends the game processing.

If the game is not completed (step S51; No), the CPU 81 sequentially receives biometric data from the biometric information acquisition device 7 via the upper terminal 31 (step S52).

Further, the CPU 81 determines whether or not the game has started (step S53).

If it is before the start of the game (step S53; No), the CPU 81 executes a baseline setting process for setting a baseline for determining whether the sympathetic nerve is dominant or the parasympathetic nerve is dominant (step S54).

FIG. 6 is a flowchart showing the details of the baseline setting process.

When the baseline setting process shown in FIG. 6 is started, the CPU 81 first performs an effect (relaxation effect) for setting the psychological state of the player to a “relaxed state” (step S61).

Next, the CPU 81 determines whether or not the player's brain wave identified from the brain wave data included in the biological data is an α wave (step S62).

If the player's brain wave is other than the α wave (step S62; No), the CPU 81 returns to step S61. On the other hand, if the player's brain wave is an alpha wave (step S62; Yes), the CPU 81 assumes that the player's psychological state is in the "relaxed state", and the pulse wave data and the pupil data included in the biometric data. Therefore, the size of the player's pulse wave and pupil in the "relaxed state" is acquired as the initial value of the biometric information (step S63).

Then, the CPU 81 sets the baseline based on the initial values of the pulse wave and the pupil size of the player acquired in step S63 (step S64), and then ends the baseline setting process.

On the other hand, after the start of the game (step S53; Yes in FIG. 5), the CPU 81 executes a psychological state flag setting process for setting the target psychological state in the psychological state flag according to the situation of the game. (Step S55).

Subsequently, the CPU 81 executes a psychological state specifying process for specifying the psychological state of the player from the combination of biological information such as the pulse wave, the brain wave, and the change of the pupil of the player (step S56).

FIG. 7 is a flowchart showing the details of the psychological state specifying process.

When the psychological state specifying process shown in FIG. 7 is started, the CPU 81 "relaxes" the player's psychological state from the combination of biological information such as the player's pulse wave, brain wave, and pupil change included in the biological data. It is specified as one of "state", "bored state", "concentrated state", and "excited state" (step S71).

If the psychological state of the player specified in step S71 is other than the "excited state" (step S72; No), the CPU 81 ends the psychological state specifying process as it is.

On the other hand, if the psychological state of the player is the "excited state" (step S72; Yes), the CPU 81 determines whether or not the duration t of the "excited state" is T1 or more (step S73). ..

If the duration t of the "excited state" is less than T1 (step S73; No), the CPU 81 ends the psychological state specifying process as it is.

On the other hand, if the duration t of the "excited state" is T1 or more (step S73; Yes), the CPU 81 specifies that the psychological state of the player is the "stress state" (step S74).

Then, the CPU 81 determines whether or not the "stress state" continues for T2 or more, that is, whether or not the duration t of the "excited state" continues for a predetermined period T1 + T2 or more (step S75).

If the duration t of the "excited state" is less than the predetermined period T1 + T2 (step S75; No), the CPU 81 ends the psychological state specifying process as it is.

On the other hand, if the duration t of the "excited state" is T1 + T2 or more for the predetermined period (step S75; Yes), the CPU 81 identifies the player's psychological state as the "fatigue state" (step S76). ), End the psychological state identification process.

Then, the CPU 81 executes a game mode change process for changing the game mode in order to bring the target psychological state set in the flag to the psychological state (step S57 shown in FIG. 5).

8 and 9 are flowcharts showing the details of the game mode change process.

In the game mode change process shown in FIGS. 8 and 9, the CPU 81 first determines whether or not the psychological state of the player specified in the psychological state specifying process in step S56 is a “fatigue state” (shown in FIG. 8). Step S81).

When the player's psychological state is "fatigue" (step S81; Yes), he advises to interrupt the game because it is impossible to immediately return the player's psychological state to a state other than "fatigue". After displaying the screen to be (instructed) (step S82), the game mode change process is terminated.

If the psychological state of the player is other than the "fatigue state" (step S81; No), the CPU 81 specifies the set value of the psychological state flag (step S83).

When the psychological state flag is set to "1" indicating "concentrated state" (step S84; Yes), if the psychological state of the player is "relaxed state" or "bored state" and the parasympathetic nerve is dominant (step S84; Yes). Step S85; Yes), the CPU 81 changes the game mode so that the sympathetic nerve is enhanced and the sympathetic nerve becomes dominant in order to bring the player's psychological state into a “concentrated state” (step S86). , The game mode change process is terminated.

On the other hand, if the psychological state of the player is a "stress state" (step S85; No, step S87; Yes), the CPU 81 suppresses the sympathetic nerve in order to return the psychological state of the player to the "concentrated state". After changing the game mode (step S88), the game mode change process ends.

On the other hand, if the psychological state of the player matches the psychological state set in the psychological state flag in the "concentrated state" (step S87; No), the CPU 81 changes the game mode in order to maintain the "concentrated state". The game mode change process is terminated as it is without performing.

On the other hand, when "2" indicating "excited state" is set in the psychological state flag (step S84; No, step S89; Yes shown in FIG. 9), the psychological state of the player is "relaxed state" or "relaxed state". If it is either a "bored state" or a "concentrated state" (step S90; Yes), the CPU 81 changes the game mode so that the sympathetic nerve is enhanced in order to make the player's psychological state "excited". (Step S91), the game mode change process is terminated.

On the other hand, if the psychological state of the player is a "stress state" (step S90; No, step S92; Yes), the CPU 81 suppresses the sympathetic nerve in order to return the psychological state of the player to the "excited state". After changing the game mode (step S93), the game mode change process ends.

On the other hand, if the psychological state of the player matches the psychological state set in the psychological state flag in the "excited state" (step S92; No), the CPU 81 changes the game mode in order to maintain the "excited state". The game mode change process is terminated as it is without performing.

On the other hand, when "3" indicating "stress state" is set in the psychological state flag (step S89; No, step S94; Yes), the psychological state of the player is "relaxed state", "bored state", If it is either a "concentrated state" or an "excited state", that is, if it is other than the "stress state" (step S95; No), the CPU 81 sympathizes with the player in order to put the psychological state into the "stress state". After the game mode is changed so as to enhance the nerve (step S96), the game mode change process is terminated.

On the other hand, if the psychological state of the player is a "stress state" (step S95; Yes), the CPU 81 ends the game mode change process as it is without changing the game mode in order to maintain the "stress state". ..

On the other hand, when "0" indicating "relaxed state" is set in the psychological state flag (step S94; No), the psychological state of the player is "concentrated state", "excited state", and "stress state". If the sympathetic nerve is in a dominant state (step S97; Yes), the CPU 81 suppresses the sympathetic nerve in order to return the player's psychological state to the "relaxed state", and the parasympathetic nerve becomes the dominant state. After changing the mode (step S98), the game mode change process is terminated.

On the other hand, if the psychological state of the player is "bored" (step S97; No, step S99; Yes), the CPU 81 causes the brain wave to become an alpha wave in order to make the player's psychological state "relaxed". After changing the game mode (step S100), the game mode change process is terminated.

On the other hand, if the psychological state of the player matches the psychological state set in the psychological state flag in the "relaxed state" (step S99; No), the CPU 81 changes the game mode in order to maintain the "relaxed state". The game mode change process is terminated as it is without performing.

As described above, the main body device 2 according to the present embodiment includes a biometric information acquisition device 7 for acquiring biometric information of a player who is a user of the game system 1, and a CPU 81 as a control unit. The CPU 81 sets the psychological state corresponding to the situation of the game being played in the psychological state flag as the psychological state to be targeted. Subsequently, the CPU 81 identifies the psychological state of the player from the biometric information acquired by the biometric information acquisition device 7. Then, the CPU 81 changes the game mode so that the psychological state specified from the biological information matches the psychological state set as the target. As a result, the main body device 2 can improve the interest in the game by changing the psychological state of the player to the psychological state corresponding to the situation of the game being played.

Specifically, in the CPU 81, when the psychological state set as a target is a state in which the sympathetic nerve is dominant, such as a "concentrated state" or an "excited state", the psychological state specified from the biological information is "relaxed". When the parasympathetic nerve is dominant, such as "state" or "boredom state", the game mode is changed so that the sympathetic nerve is enhanced. On the other hand, in the CPU 81, when the psychological state set as a target is a state in which the parasympathetic nerve is dominant, such as a "relaxed state" or a "boredom state", the psychological state specified from the biological information is a "concentrated state". When the sympathetic nerve is dominant, such as in an "excited state" or "excited state", the game mode is changed so that the sympathetic nerve is suppressed. On the other hand, the CPU 81 does not change the game mode when the psychological state specified from the biological information matches the psychological state set as the target. In this way, the main body device 2 can improve the interest in the game by changing the psychological state of the player to the psychological state corresponding to the situation of the game being played.

The CPU 81 sets a baseline for determining whether the player's psychological state is superior to the sympathetic nerve or the parasympathetic nerve, based on the biological information acquired by the biological information acquisition device 7 before the start of the game. .. Then, the CPU 81 determines that the sympathetic nerve is in a predominant state when the biometric information acquired by the biometric information acquisition device 7 during game play is above the baseline, and when it is below the baseline, the parasympathetic nerve. Is determined to be in a superior state. As described above, the main body device 2 sets a baseline for determining whether the player's psychological state is the predominant state of the sympathetic nerve or the parasympathetic nerve, based on the biological information acquired before the start of the game. It can be set accurately.

The CPU 81 identifies the player's psychological state as a relaxed state when the player's brain wave identified from the biometric information acquired by the biometric information acquisition device 7 is an α wave, and is in a bored state when the player's psychological state is a θ wave. To specify. The CPU 81 changes the game mode so that the player's brain wave becomes an α wave when the psychological state set as the target is a relaxed state and the psychological state specified from the biological information is a bored state. Thereby, the main body device 2 can prevent the player from getting bored with the game.

When the brain wave of the player specified from the biometric information acquired by the biometric information acquisition device 7 is a gamma wave, the CPU 81 identifies the psychological state of the player as an excited state. Then, when the excitement state continues for T1 + T2 or more for a predetermined period, the CPU 81 considers that the psychological state of the player (user) is in a fatigue state and it is difficult to achieve the psychological state set as the target. Instruct the player to suspend. As described above, the main body device 2 can recover the fatigue of the player at an early stage by causing the player to interrupt the game, and can set the psychological state of the player to the psychological state set as the target after the game is restarted.
